Abstract

The MESH version r1589_RTE_ts450s was used. This version of MESH has a hybrid functionality which allows users to define different grid specifications for routing scheme and land surface scheme. Here, in our model, routing scheme has a cell resolution of 0.0083 degree and land surface scheme has a resolution of 0.09 degree. The model includes 13 Ground Response Unit (GRU) classes. The Digital Elevation Models (DEM) was downloaded from USGS HydroSHEDS database with 30 arc-second resolution. Soil data was obtained from Global Soil Dataset for Earth System Models (Shangguan et al. 2014) ( http://globalchange.bnu.edu.cn/research/soilw ) and the landcover data was obtained from Climate Change Initiative (CCI) Land Cover 2015. The forcing data was extracted from the Global Environmental Multiscale atmospheric model and the Canadian Precipitation Analysis (GEM-CaPA) which a high-resolution gridded database.

Purpose

The main goal of this project is to accurately estimate streamflow from creeks and tributaries to the main stem of Grand River. The estimated streamflow will be used to estimate non-point nitrogen loads to the main stem of the river and in order to improve the estimation of nitrogen loads from Grand River to Lake Erie. This project supports the Water Quality Modelling theme of the Core Modelling and Forecasting Team.
